My inuonlion. pertains to in'prmmnzonts in Wlmt may ho (12: ednut-incline, its objvot is to pro-writ tho uroidoiunl liI)sn l(W- ing ordispluoonzont of tho nut, pm'tioulnrly i FfiJll'l tho transmitting of njarring srtion or othi-rwise, and in Fttlfliti'im to provide for thoready u 'splimtion of tho nuts and the in'lorloolring of tho so no andtizoir carryingbolt, and, further, to hurry out those (not in u sinploovono I in. and oll'rxrlii' n miner.

In tho accompanying drnwin illustrating the preferred unhodimont of myinvention, Figure l is at 'VlLW showing it as applied to a bolt forpractical use. Fig. 2 is a crosssootion taken through the bolt viewingthe some from the nut-equipped 0nd. Fig. 3 is it longitudinal section inpart and partly in side viow. Fig. l'is :1 viov ol the hashing-nut withthe key in position then-in as in unlooking or withdrawing the springetainod pin or detent from the bolt. Fig. 5 shows said nut with itsadjunctive parts disassem ble in praoticing my invontion l employa boltduvod in the not 4.

Said not 4 is oquippod with :1, pin or dotont 5, havin;nour its outor end a lateral notrh or sookot 5", tho purpose of whiohwill lotor appear, and whioh dotont or pin is arranged to normallyproject into tho holt passaigo of the nut and ontoring or engaging thorequisite or -rog istoring one of the series of notches or grooves 2 oitho bolt 1, according to tho position said pin or dotent may ussuniowhen tho nut 4 has roziolu'd tho nut 31 in SCI'CWlIlt-j it home.

Said rl suro or plate 8 has produrod thvrvin :in inverted-Lform of slot 9, with ouo portion or log opposed to tho notch or sot'ket5 of the pin or dotont 5, and fitted to operate in this slot is a key10, having a ldtOIill bit or stud 10, adopted to be hrought intoregister or ongng enmnt with the lateral arm of the slot 9, as presentlydisclosed.

Itis noted that with the parts or nuts in position upon the bolt, asaforesaid, the detont 5 is ellertive for their retention in normalposition against any possible displacement from any jarring notion whichmay be trmisniittml tlivrvto, and yot they are readily remoynblo. Thishitter may be easily acv olnplishod by the aid of tho key 10 byinserting its stain portion through the slot 9 in the srutcheon-plate 8,ndjunotive of the nut 4, and into the lateral notch or socket 5 of the(letont or pin 5 and thou forcing upward upon tho key until its bit orstud 10 is brought into nlinomont with the lateral portion or arm ofsaid slot, when by rotating the key and pushing it inward or at rightangles to its 'n'ovious movement the bit of the key is lodgod within thearm of the slot.
